Introduction: Kidney cancer corresponds to the 13th most incident cancer in the world, and the third most common type of genitourinary cancer. Most patients are asymptomatic, and the diagnosis used to be incidental during routine imaging exams. Surgical treatment is the gold standard. Objective: To correlate clinical and pathological parameters with disease-free survival in renal cancer patients submitted to nephrectomy. Method: Retrospective study with 99 patients who underwent surgical treatment of kidney cancer from 2010 to 2020. Clinical and pathological parameters were compared with the clinical oncologic outcome after surgery. Results: Ninety-nine patients were followed-up postoperatively for an average time of 26.9 months, and the mean disease-free survival was 61.9%. Univariate analysis showed that tumor size >7 cm and Fuhrman grades III and IV were risk factors related to disease progression after nephrectomy (p=0.046 and CI=1.017-7.083; p=0.005 and CI=1.725-23.004, respectively). In the multivariate analysis, tumor size > 7cm (p=0.014 and CI=1.290-9.326) and Fuhrman grades III and IV (p=0.028 and CI=1.174-16.616) were identified as predictors of progression. Conclusion: Tumor size >7 cm and/or Fuhrman grades III or IV are risk factors for tumor recurrence after surgical treatment of renal cancer.
